WILLIAM H. LOGAN, OF CARNEGIE, PENNSYLVANIA.

MINERS LAMP.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed November 22, 1912. Serial No. 732,812.

T 0 all whom it may concern Be it known that 1, WILLIAM H. LOGAN, a citizen of the United States of America, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have in vented certain new and useful Improvements in Miners Lamps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to miners lamps, and the objects of my invention are to provide :---First, a miners lamp having a spout capable of holding in suspension a quantity of grease or oil to facilitate a rapid ignition of a wick within the spout. Second, a lamp spout that has an oblong wick outlet opening at right angles to the vertical axis of the lamp. Third, a miners lamp in connection with which an ordinary grease or heavy oil can be used without any danger of drippings. Fourth, a miners lamp that is inexpensive to manufacture, durable, and highly efficient for the purposes for which it is intended.

My invention further aims to accomplish the above results by a mechanical construction that will be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a side elevation of the lamp, Fig. 2 is a front elevation of the same, Fig. 3 is a plan of the lamp, and Fig. l is an enlarged longitudinal sectional. view of a portion of the spout of the lamp.

A lamp in accordance with this invention comprises a frusto-conical shaped receptacle 1 having a hinged lid 2 and a hook or support 3 whereby the lamp can be attached to a cap. The lamp is preferably made of aluminum and the front side thereof has an inclined spout i. The inner end of the spout is of greater cross sectional area than the outer end thereof and the outer end of the spout is flattened or flared at its sides whereby the same will present an oblong wick outlet opening 5 for a wick 6. The opening 5 is at right angles to the longitudinal axis of the spout and the front wall of said opening at the end of said wall is bent inwardly, the said bent portion constitutes a lip 7 that prevents grease or oil from dripping from the spout. The inner wall of the opening 5, at a point removed from the outer end of the spout has a transverse groove 8 forming a collector for a quantity of grease or oil. After the wick is extinguished a quantity of grease or oil will accumulate in the groove 8 and remain in said groove to be drawn by a capillary attraction to the end of the wick when said wick is again ignited.

By actual. use I have found that when the wick of an ordinary minors lamp is extinguished that the grease or oil will flow back in the spout or into the lamp leaving the wick in a state not conducive to rapid ignition, and that it is a period of time before the lamp is in proper working order and the wick fed with a desired amount of grease or oil. By my improvement there is always asmall quantity of grease or oil held in suspension that permits the end of the wick being immediately ignited and with the wick flattened out I obtain a more brilliant flame than the flame of an ordinary miners lamp. It is these advantages to which I attach considerable importance as there is a reduction in the waste of wicks, preparation and maintenance of lamps are reduced to a minimum and perfect safety as sured.

hile in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements are susceptible to such modifications and variations as fall within the scope of the appended claims.

What I claim is 1. A miners lamp having an inclined wick tube with the inner end thereof of greater cross section than the area of the outer end, the outer portion of said tube being flattened and said flattened portion gradually flaring from its inner terminus to its outer terminus, said flattened portion being ovalshaped in cross section, the front wall of said flattened portion having its outer terminus bent inwardly to provide a lip.

2. A miners lamp having its spout formed with an ovalshaped outlet, the wall at the front side of said outlet extending inwardly to provide a lip.

In testimony whereof I atlix my signature in the presence of two witnesses.

WILLIAM H. LOGAN.
